Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 100 words
A textile material useful for articles of clothing, curtains, or coatings in which the chromatic effect is variable with environmental conditions to produce decorative effects, comprising a support consisting of a dark fabric, leather or hide having on at least one surface thereof a layer of a microencapsulated liquid cholesteric crystal composition including: cholesteryl nonanoate: 73-80 parts by weight oleyl cholesteryl carbonate: 5-12 parts by weight cholesteryl chloride: 15 to 15.6 parts by weight; and said crystal composition being adapted to change from a transparent state to a colored state within a given temperature range in response to environmental conditions.
Claim 2
Dependent Claim 100 words
